This article presents a novel metal bezel antenna structure and its performance in user vicinity. The antenna is designed by keeping in mind the insensitivity in usage environments. In the antenna structure, a mobile chassis and a bezel are combined as one antenna element. Symmetrical feeding is used to excite the antenna. The characteristics of the metal bezel are compared with those of a conventional planar inverted-F antenna in terms of user effect at E-GSM band (880-960 MHz). Both antennas are measured and compared with four different hand phantom grips representing a browsing mode. The grips are designed so that the chassis is under the hand phantom in different variable usage conditions. Results are compared in terms of S-11, total efficiency, total body loss, radiation efficiency, reflection loss, and in Smith chart presentation. Finally, antenna structures are compared with hand and head phantom measurements representing a calling mode. The comparison is done in terms of average total body loss. The used hand grips are the same as in the case of the hand phantom measurements.
